On the Uniqueness and Causal Relationship of Precursor Activity to Solar Energetic Events: I. Transient Brightenings -- Introduction and Overview

Karin Dissauer, Graham Barnes, KD Leka +1

The physical role played by small-scale activity that occurs before the sudden onset of solar energetic events (SEEs, i.e., solar flares and coronal mass ejections) remains in ques…

Evaluating (and Improving) Estimates of the Solar Radial Magnetic Field Component from Line-of-Sight Magnetograms

K. D. Leka, G. Barnes, E. L. Wagner

Although for many solar physics problems the desirable or meaningful boundary is the radial component of the magnetic field , the most readily available measurement is t…

A Fixed-point Scheme for the Numerical Construction of Magnetohydrostatic Atmospheres in Three Dimensions

S. A. Gilchrist, D. C. Braun, G. Barnes

Magnetohydrostatic models of the solar atmosphere are often based on idealized analytic solutions because the underlying equations are too difficult to solve in full generality. Nu…

The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: Optimization of the Spectral Line Inversion Code

R. Centeno, J. Schou, K. Hayashi +5

The Very Fast Inversion of the Stokes Vector (VFISV) is a Milne-Eddington spectral line inversion code used to determine the magnetic and thermodynamic parameters of the solar phot…

Helioseismology of Pre-Emerging Active Regions III: Statistical Analysis

G. Barnes, A. C. Birch, K. D. Leka +1

The subsurface properties of active regions prior to their appearance at the solar surface may shed light on the process of active region formation. Helioseismic holography has bee…
